Walnut Heights is an affluent unincorporated community in Contra Costa County, California, United States. It is located at an elevation of 200 feet (61m), in the hills near Walnut Creek. The ZIP Code is 94596. The community is inside area code 925. It is served by Walnut Heights Elementary School, Walnut Creek Intermediate, and Las Lomas High School.

The area was once a rancho, Rancho del Arroyo de las Bobones, owned by Maria Castro during Mexico's era of rule over California. She had a nephew named Ygnacio, which Ygnacio Valley and Ygnacio Valley Road were named for. Rancho del Arroyo de las Bobones is roughly translated in English 'Walnuts of the Creek Ranch'.

After the Bear Flag Revolt and California's short-lived independence as a sovereign state, the ranchos across the new nation were abandoned including Walnut Heights' rancho. After a month, California got wars and civil unrest between Mexico and the United States. There were many tensions, and thousands got fatalities, prompting California to become once again unorganized and unincorporated.

During the Gold Rush era, the white men from the east coast captured the ranchos and more ranches and farms plus corrals were built. However, the new people did not like California as an unorganized unincorporated land, and that prompted California to join the union as a state.
